CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of the Korean Patent Application No. 10-2020-0189806 filed on Dec. 31, 2020, which is hereby incorporated by reference in its entirety as if fully set forth herein.

BACKGROUND Field of the Disclosure

The present disclosure relates to a sliding display apparatus.

Description of the Related Art

Recently, rollable display apparatuses are being released by using a characteristic where a light emitting display panel is rolled. However, in rollable display apparatuses, because a light emitting display panel should be rolled, a space for enabling the light emitting display panel to be rolled is needed, and due to this, a height of a display apparatus should increase.

When a height of a display apparatus increases, it is difficult to mount a display apparatus on things such as desks.

SUMMARY

Accordingly, the present disclosure is directed to providing a sliding display apparatus that substantially obviates one or more problems due to limitations and disadvantages of the related art.

More specifically, the present disclosure is directed to providing a sliding display apparatus in which a display panel unfolded in a case may be exposed in a direction toward an upper end of the case.

To achieve these and other advantages of the inventive concepts, as embodied and broadly described herein, a sliding display apparatus comprises a display panel including first to fourth side surfaces, a case configured to accommodate the display panel, a cover configured to cover an opened upper surface of the case and including a hole provided at one side thereof, a wire driving part connected to at least one wire connected to a lower surface of the display panel, and a sliding controlling part configured to control the wire driving part, and an upper portion of the display panel is exposed through the hole provided at the cover.

Other systems, methods, features and advantages will be, or will become, apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the present disclosure, and be protected by the following claims. Nothing in this section should be taken as a limitation on those claims. Further aspects and advantages are discussed below in conjunction with aspects of the disclosure.

It is to be understood that both the foregoing general description and the following detailed description of the present disclosure are exemplary and explanatory and are intended to provide further explanation of the inventive concept as claimed.

DETAILED DESCRIPTION

Reference will now be made in detail to aspects of the present disclosure, examples of which may be illustrated in the accompanying drawings. In the following description, when a detailed description of well-known functions or configurations related to this document is determined to unnecessarily cloud a gist of the inventive concept, the detailed description thereof will be omitted. The progression of processing steps and/or operations described is an example; however, the sequence of steps and/or operations is not limited to that set forth herein and may be changed as is known in the art, with the exception of steps and/or operations necessarily occurring in a particular order. Like reference numerals designate like elements throughout. Names of the respective elements used in the following explanations are selected only for convenience of writing the specification and may be thus different from those used in actual products.

Advantages and features of the present disclosure, and implementation methods thereof will be clarified through following aspects described with reference to the accompanying drawings. The present disclosure may, however, be embodied in different forms and should not be construed as limited to the aspects set forth herein. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Further, the present disclosure is only defined by scopes of claims.

A shape, a size, a ratio, an angle, and a number disclosed in the drawings for describing aspects of the present disclosure are merely an example, and thus, the present disclosure is not limited to the illustrated details. Like reference numerals refer to like elements throughout. In the following description, when the detailed description of the relevant known function or configuration is determined to unnecessarily obscure the important point of the present disclosure, the detailed description will be omitted.

In a case where “comprise,” “have,” and “include” described in the present specification are used, another part may be added unless “only” is used. The terms of a singular form may include plural forms unless referred to the contrary.

In construing an element, the element is construed as including an error or tolerance range although there is no explicit description of such an error or tolerance range.

In describing a position relationship, for example, when a position relation between two parts is described as “on,” “over,” “under,” and “next,” one or more other parts may be disposed between the two parts unless a more limiting term, such as “just” or “direct(ly)” is used.

In describing a time relationship, for example, when the temporal order is described as, for example, “after,” “subsequent,” “next,” and “before,” a case which is not continuous may be included unless a more limiting term, such as “just,” “immediate(ly),” or “direct(ly)” is used.

It will be understood that, although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present disclosure.

In describing the elements of the present disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to identify the corresponding elements from the other elements, and basis, order, or number of the corresponding elements should not be limited by these terms. The expression that an element or layer is “connected,” “coupled,” or “adhered” to another element or layer means that the element or layer can not only be directly connected or adhered to another element or layer, but also be indirectly connected or adhered to another element or layer with one or more intervening elements or layers “disposed” between the elements or layers, unless otherwise specified.

The term “at least one” should be understood as including any and all combinations of one or more of the associated listed elements. For example, the meaning of “at least one of a first element, a second element, and a third element” denotes the combination of all elements proposed from two or more of the first element, the second element, and the third element as well as the first element, the second element, or the third element.

In the description of aspects, when a structure is described as being positioned “on or above” or “under or below” another structure, this description should be construed as including a case in which the structures contact each other as well as a case in which a third structure is disposed therebetween. The size and thickness of each element shown in the drawings are given merely for the convenience of description, and aspects of the present disclosure are not limited thereto, unless otherwise specified.

Features of various aspects of the present disclosure may be partially or overall coupled to or combined with each other, and may be variously inter-operated with each other and driven technically as those skilled in the art can sufficiently understand. The aspects of the present disclosure may be carried out independently from each other, or may be carried out together in co-dependent relationship.

Hereinafter, aspects of the present disclosure will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a display panel applied to a sliding display apparatus according to an aspect of the present disclosure, and FIG. 2 illustrates a side surface of a display panel applied to the sliding display apparatus according to an aspect of the present disclosure.

For example, one end of the first wire 310 a may be fixed to the first fixing part 310 b through soldering. One side of the second wire 320 a may be fixed to the second fixing part 320 b through soldering. For example, one end of the second wire 320 a may be fixed to the second fixing part 320 b through soldering.

The panel driving part 200 may include a gate driver, a data driver 220, and a panel controlling part 240. The gate driver may supply gate pulses to the gate lines included in the panel 110. For example, the gate driver may be configured with an integrated circuit (IC) and may be disposed at a non-display area of the panel 110, or may be configured with an IC and may be disposed at a flexible film 210. Alternatively, the gate driver may be directly embedded into the non-display area by using a gate-in panel (GIP) type.

The data driver 220 may supply data voltages to the data lines included in the panel 110. For example, the data driver 220 may be configured with an IC and may be disposed at the non-display area of the panel 110, or may be configured with an IC and may be disposed at the flexible film 210. Alternatively, the data driver 220 may be directly embedded into the non-display area.

The gate driver and the data driver 220 may be disposed at different flexible films, or may be disposed at one flexible film 210. For example, in FIGS. 1 and 2, the driver 200 where only the panel driving part 220 is disposed at the flexible film 210 is illustrated, but aspects of the present disclosure are not limited thereto. For example, the gate driver and the data driver 220 may all be disposed at one flexible film 210.

The flexible film 210, on which at least one of the gate driver and the data driver 220 is disposed, may be attached on a printed circuit board (PCB) 230 and may be electrically connected to the panel controlling part 240 disposed at the PCB 230.

The panel controlling part 240 may control the gate driver and the data driver 220. The panel driving part 240 may be connected to an external system which controls the sliding display apparatus according to an aspect of the present disclosure.

For example, the panel controlling part 240 may realign pieces of input video data transferred from an external system based on a timing synchronization signal transferred from the external system. The panel controlling part 240 may include a data align part, a control signal generating part, an input part, and an output part. The data align part may supply pieces of realigned image data to the data driver 220. The control signal generating part may generate a gate control signal and a data control signal based on the timing synchronization signal. The input part may receive the timing synchronization signal and the pieces of input video data transferred from the external system. The output part may output the pieces of image data generated by the data align part and control signals, generated by the control signal generating part, to the data driver 220 or the gate driver. The gate control signal may be a signal which controls the gate driver, and the data control signal may be a signal which controls the data driver 220.

For example, a lower surface formed by the first to fourth sidewalls 11 to 14 may be covered by the lower wall 15, and an upper surface formed by the first to fourth sidewalls 11 to 14 may be covered by the cover 20.

The display panel 100 may be provided on an upper surface of the lower wall 15.

Subsequently, the cover 20 may cover the upper surface (for example, an opened upper surface of the case 10 formed by the first to fourth sidewalls 11 to 14).

The hole 21 through which the display panel 100 comes up may be provided at one side (for example, a first side) of the cover 20. The hole 21 may be provided at the cover 20 along the first sidewall 11 of the case 10.

For example, a size of the hole 21 may be adjusted to a size which enables the upper portion or the second portion of the display panel 100 to be come up.

For example, a length of the hole 21 formed in a direction from the third sidewall 13 of the case 10 to the fourth sidewall 14 of the case 10 may be adjusted to be greater than that of the upper portion or the second portion of the display panel 100.

A width of the hole 21 formed in a direction from the first sidewall 11 of the case 10 to the second sidewall 12 of the case 10 may be adjusted to be greater than that of the upper portion of the display panel 100, for example, a thickness of the display panel 100.

Subsequently, the wire driving parts 610 and 620 may be connected to the one or more wires 310 a and 320 a connected to the lower surface of the display panel 100.

For example, as described above, the one or more wires 310 a and 320 a may be disposed at a lower surface of the back plate 120 configuring the display panel 100. For example, in FIG. 1, the display panel 100 where the first wire 310 a and the second wire 320 a are provided is illustrated for an aspect of the present disclosure. In this case, the first fixing part 310 b connected to the first wire 310 a may be provided at one side of the lower surface of the back plate 120. For example, the first fixing part 310 b connected to the first wire 310 a may be provided at the end of the one side or the one side of the lower surface of the back plate 120. The second fixing part 320 b connected to the second wire 320 a may be provided at the other side of the lower surface of the back plate 120. For example, the second fixing part 320 b connected to the second wire 320 a may be provided at the end of the other side or the other side of the lower surface of the back plate 120.

In this case, the wire driving part may include a first rotation part 610 which is disposed at one side of an inner portion of the case and is connected to the first wire 310 a and a second rotation part 620 which is disposed at the other side of the inner portion of the case and is connected to the second wire 320 a.

For example, the first rotation part 610 may be disposed at one side of the inner portion of the case. The first rotation part 610 may be connected to the first wire 310 a connected to one side of the lower surface of the display panel 100. For example, the first rotation part 610 may be connected to the first wire 310 a connected to an end of the one side of the lower surface of the display panel 100.

The second rotation part 620 may be disposed at the other side of the inner portion of the case. The second rotation part 620 may be connected to the second wire 320 a connected to the other side of the lower surface of the display panel 100. For example, the second rotation part 620 may be connected to the second wire 320 a connected to the end of the other side of the lower surface of the display panel 100.

The one side of the inner portion of the case, for example, may be a portion, connected to the second sidewall 12 and the third sidewall 13, among an upper surface of the lower wall 15. The other side of the inner portion of the case, for example, may be a portion, connected to the second sidewall 12 and the fourth sidewall 14, among the upper surface of the lower wall 15.

For example, in FIGS. 3 to 5, the one side of the inner portion of the case may be a left lower portion of the lower wall 15, and the other side of the inner portion of the case may be a right lower portion of the lower wall 15.

Each of the first rotation part 610 and the second rotation part 620 may be a motor.

Finally, the sliding controlling part 30 may control the wire driving part 610 and 620.

For example, the first rotation part 610 and the second rotation part 620 may be driven by the sliding controlling part 30.

To this end, the sliding controlling part 30 may be connected to the first rotation part 610 and the second rotation part 620.

The sliding controlling part 30 may be a wireless controller which is driven by a remote controller or a button, to turn on or off the first rotation part 610 and the second rotation part 620.

For example, a user may directly touch a button configuring the sliding controlling part 30 to drive the wire driving parts 610 and 620. Also, the user may transmit a wireless control signal to the sliding controlling part 30 by using a remote controller, and the wire driving parts 610 and 620 may be driven by the sliding controlling part 30 which has received the wireless control signal. The first rotation part 610 and the second rotation part 620 included in the wire driving parts 610 and 620 may be simultaneously driven.

The sliding controlling part 30 may perform communication with the external system.

For example, when the sliding controlling part 30 is turned on based on the button or the wireless control signal, the external system may also be turned on, and thus, the panel driving part 200 may operate.

A hole 21 may be provided at the cover 20 along the roller 800, in a region adjacent to the first sidewall 11 of the case 10.

The display panel 100 may be come up from the hole 21 through a space between the first sidewall 11 of the case 10 and the roller 800.

The sliding display apparatus according to an aspect of the present disclosure may further include at least one transport roller 500. In FIG. 6, the sliding display apparatus including four transport rollers 500 is illustrated as an aspect of the present disclosure.

The transport roller 500 may be provided at the lower wall 15 of the case 10 and may support the display panel 100.

The transport roller 500 may extend in a direction from the first sidewall 11 to the second sidewall 12. For example, the transport roller 500 may be disposed in parallel with the third sidewall 13 or the fourth sidewall 14.

The display panel 100 may be provided at an upper portion of the at least one transport roller 500. For example, the display panel 100 may be transported in a direction of the third sidewall 13 or the fourth sidewall 14 in a state which is supported by the transport roller 500.

In this case, both side surfaces of the display panel 100 may be guided by the first guide roller 410 and the second guide roller 420.

For example, the display panel 100 may be disposed between the first guide roller 410 and the second guide roller 420 and may be transported in a direction toward the first sidewall 11 along the transport roller 500. An upper portion of the display panel 100 transported in the direction toward the first sidewall 11 may be come up through the hole 21.

Moreover, the display panel 100 may be disposed between the first guide roller 410 and the second guide roller 420 and may be transported in a direction toward the second sidewall 12 along the transport roller 500. Also, the display panel 100 may be provided at an upper end of the transport roller 500.

FIGS. 7 and 8 illustrate a first sidewall of a sliding display apparatus according to an aspect of the present disclosure, and for example, are exemplary diagrams illustrating a sliding display apparatus where a display panel 100 is accommodated into an inner space thereof. FIGS. 9 and 10 illustrate a first sidewall of a sliding display apparatus according to another aspect of the present disclosure, and for example, are exemplary diagrams illustrating a sliding display apparatus where a display panel 100 is exposed in a direction toward an upper end of a cover 20 through a hole 21.

A case 10 may include a first sidewall 11, a second sidewall 12, a third sidewall 13, a fourth sidewall 14, and a lower wall 15. The display panel 100 may include a first side surface, a second side surface, a third side surface, and a fourth side surface. The first side surface may be adjacent to the first sidewall 11, the second side surface may be adjacent to the second sidewall 12, the third side surface may be adjacent to the third sidewall 13, and the fourth side surface may be adjacent to the fourth sidewall 14. An upper portion of the display panel 100 (for example, a portion corresponding to the first side surface) may be exposed at the outside through a hole 21 formed at a portion, which is adjacent to the first sidewall 11, of the cover 20.

A link guide 730 may be disposed at a rear surface of an upper portion, exposed through the hole 21, of the display panel 100 in parallel with the hole 21. For example, the link guide 730 may be disposed on a lower surface of an upper portion of the display panel 100, for example, a lower surface of an upper portion of a back plate 120.

The link guide 730 may be disposed at a lower surface of the upper portion of the back plate 120 along the first side surface of the display panel 100. In this case, a length of the link guide 730 may be less than or equal to that of the first side surface.

One side or one end of a first link 710 may be disposed to be rotatable in a first region 11 a of the first sidewall 11, which is adjacent to the hole 21, among the case 10. One side or one end of a second link 720 may be disposed to be rotatable in a second region 11 b of the first sidewall 11. Also, the other side or the other end of the first link 710 may be connected to the link guide 730, and the other side or the other end of the second link 720 may be connected to the link guide 730.

For example, the one side or the one end of the first link 710 may be disposed to be rotatable at the first region 11 a of the first sidewall 11, and the other side or the other end of the first link 710 may be connected to the link guide 730. Also, the one side or the one end of the second link 720 may be disposed to be rotatable at the second region 11 b of the first sidewall 11, and the other side or the other end of the second link 720 may be connected to the link guide 730.

For example, the other side or the other end of the first link 710 and the other side or the other end of the second link 720 may be disposed to face each other in the link guide 730. The other side or the other end of the first link 710 and the other side or the other end of the second link 720 may move along the link guide 730.

To this end, a first link bar 710 a disposed to be rotatable at the other side or the other end of the first link 710 may be inserted or accommodated into a groove 731 of the link guide 730. A second link bar 720 a disposed to be rotatable at the other side or the other end of the second link 720 may be inserted or accommodated into the groove 731 of the link guide 730.

For example, as the first link bar 710 a rotates in the groove 731 of the link guide 730, the first link 710 may move along the groove 731 of the link guide 730. As the second link bar 720 a rotates in the groove 731 of the link guide 730, the second link 720 may move along the groove 731 of the link guide 730.

The first sidewall 11 may include a first region 11 a, a second region 11 b, and a third region 11 c between the first region 11 a and the second region 11 b. For example, the link guide 730 may be supported by the third region 11 c.

For example, as illustrated in FIGS. 7 and 8, when only an upper portion of the display panel 100 is exposed through the hole 21, the link guide 730 may be supported by the third region 11 c. Therefore, the display panel 100 may not be inserted or accommodated into the hole 21. In this case, the first link 710 and the second link 720 may be disposed to face each other at a center portion of the link guide 730.

Moreover, when the display panel 100 comes up in an upward direction of a cover 20 through the hole 21, the first link 710 and the second link 720 may be progressively farther away from the center portion of the link guide 730 and may be disposed at a position illustrated in FIGS. 9 and 10.

Therefore, the display panel 100 come up through the hole 21 may be maintained in a tight state by the first link 710, the second link 720, and the link guide 730.

FIG. 11 illustrate a front of a sliding display apparatus according to an aspect of the present disclosure, and for example, are exemplary diagrams illustrating a sliding display apparatus where a display panel 100 is completely exposed in an upward direction of a cover 20 through a hole 21. FIG. 3 illustrates a sliding display apparatus where a display panel 100 is accommodated into an inner space of a case 10, and FIG. 10 illustrates a sliding display apparatus where most portions of a display panel 100 are completely come up through a discharging hole 21.

Hereinafter, a process of come up a display panel to the outside of a sliding display apparatus through a hole 21 and a process of inserting or accommodating the display panel into the sliding display apparatus through the hole 21 will be described with reference to FIGS. 1 to 11. In the following description, descriptions which are the same as or similar to descriptions given above with reference to FIGS. 1 to 10 are omitted or will be briefly given.

As illustrated in FIGS. 7 and 8, when most portions of the display panel 100 are inserted or accommodated into an inner space formed by the case 10 and the cover 20, only the upper portion of the display panel 100 may be exposed through the hole 21.

In this case, the link guide 730 may be supported by the third region 11 c. Therefore, the display panel 100 may not be inserted or accommodated into the hole 21. In this case, the first link 710 and the second link 720 may be disposed to face each other at the center portion of the link guide 730. Accordingly, the first link 710 and the second link 720 may no longer move along the link guide 730, and thus, the display panel 100 may no longer be inserted or accommodated into the hole 21.

For example, the display panel 100 may not be inserted or accommodated into the case by the link guide 730, and moreover, may not be inserted or accommodated into the case by the first link 710, the second link 720, and the link guide 730.

Subsequently, when a user turns on a button or a switch included in the sliding controlling part 30 or transmits, to the sliding controlling part 30, a wireless control signal for turning on the sliding controlling part 30 by using a remote controller, the sliding controlling part 30 may be turned on.

When the sliding controlling part 30 is turned on, the sliding controlling part 30 may drive the first rotation part 610 and the second rotation part 620.

Subsequently, when the first rotation part 610 is driven by the sliding controlling part 30, a motor configuring the first rotation part 610 may rotate, and thus, the first wire 310 a may be drawn to the first rotation part 610 and may be wound around the first rotation part 610.

When the second rotation part 620 is driven by the sliding controlling part 30, a motor configuring the second rotation part 620 may rotate, and thus, the second wire 320 a may be drawn to the second rotation part 620 and may be wound around the second rotation part 620.

Subsequently, the first wire 310 a may be connected to the first fixing part 310 b provided in a second lateral direction of the display panel 100, for example, adjacent to the second sidewall 12 and may extend in a direction toward the first sidewall 11 along the first guide roller 410. The first wire 310 a may be bent by the adjacent first guide roller 410 in a direction toward the first sidewall 11 and may be again connected to the first rotation part 610 provided in a direction toward the second sidewall 12.

The second wire 320 a may be connected to the second fixing part 320 b provided at a position in the second lateral direction of the display panel 100, for example, the adjacent to second sidewall 12 and may extend in the direction toward the first sidewall 11 along the second guide roller 420. The second wire 320 a may be bent by the adjacent second guide roller 420 in a direction toward the first sidewall 11 and may be again connected to the second rotation part 620 provided in a direction toward the second sidewall 12.

Therefore, when the first wire 310 a is wound around the first rotation part 610 and the second wire 320 a is wound around the second rotation part 620, the second side surface of the display panel 100 may move in the direction toward the first sidewall 11 along the first wire 310 a and the second wire 320 a. For example, when the first wire 310 a is wound around the first rotation part 610 and the second wire 320 a is wound around the second rotation part 620, the display panel 100 may move in a direction from the second sidewall 12 to the first sidewall 11.

Subsequently, the display panel 100 which has moved in the direction toward the first sidewall 11 may come up in the upward direction of the cover 20 through the hole 21.

For example, the display panel 100 which has moved in the direction toward the first sidewall 11 may come up from the hole 21 through a space between the first sidewall 11 of the case 10 and the roller 800.

Here, the upward direction of the cover 20 may be a direction vertical to a plane of the cover 20. However, the display panel 100 come up in the upward direction of the cover 20 may not denote that the display panel 100 comes up the direction vertical to the plane of the cover 20. For example, the display panel 100 may come up in the direction vertical to the plane of the cover 20, and for example, may come up at various angles with respect to the cover 20. An angle, by which the display panel 100 is inclined with respect to the plane of the cover 20, may be variously adjusted based on lengths or angles of the first link 710 and the second link 720.

Subsequently, when the display panel 100 comes up in the upward direction of the cover 20, the other end of the first link 710 and the other side or the other end of the second link 720 adjacent to each other at a center portion of the link guide 730 may be spaced apart from each other.

For example, when the display panel 100 comes up in the upward direction of the cover 20, the upper portion of the display panel 100 may be progressively farther away from the cover 20. Also, the link guide 730 disposed at the display panel 100 may be progressively farther away from the cover 20.

Therefore, the first link 710 and the second link 720 may move in a direction vertical to an upper surface of the cover 20. Accordingly, the other side or the other end of the first link 710 and the other side or the other end of the second link 720 adjacent to each other at the center portion of the link guide 730may be progressively farther away from each other.

Subsequently, when the display panel 100 maximally comes up in the upward direction of the cover 20, as illustrated in FIGS. 9 to 10, the other side or the other end of the first link 710 may contact one end of the link guide 730, and the other side or the other end of the second link 720 may contact the other end of the link guide 730.

For example, the first link 710 and the second link 720 may be spaced apart from the center portion of the link guide 730 by a maximum distance. Accordingly, the first link 710 and the second link 720 may no longer move along the link guide 730.

That the first link 710 and the second link 720 do not move along the link guide 730 any longer may denote that the display panel 100 maximally comes up through the hole 21.

In this state, the display panel 100 may be driven by the panel driving part 200 and may display an image.

Therefore, in a state illustrated in FIGS. 9 to 11, a user may watch an image displayed by the display panel 100.

Finally, when a user turns off a button or a switch included in the sliding controlling part 30 or transmits, to the sliding controlling part 30, a wireless control signal for turning off the sliding controlling part 30 by using the remote controller, the sliding controlling part 30 may be turned off, and thus, operations described above may be performed in reverse order.

For example, the first link 710 and the second link 720 may move toward the center portion of the link guide 730 to get closer to each other, and thus, a height of the upper portion of the display panel 100 may be progressively reduced.

In this case, a motor configuring the first rotation part 610 and the second rotation part 620 may rotate in a second direction opposite to a first direction, and thus, the first wire 310 a and the second wire 320 a may be unwound from the first rotation part 610 and the second rotation part 620.

For example, when the first link 710, the second link 720, and the link guide 730 are lowered by gravity in a direction toward the first sidewall 11, the first wire 310 a and the second wire 320 a may be unwound from the first rotation part 610 and the second rotation part 620. Accordingly, the second side surface of the display panel 100 may move in a direction from the first sidewall 11 to the second sidewall 12.

When the first link 710 and the second link 720 face each other at the center portion of the third link 730 and link guide 730 is supported by the first sidewall 11, the display panel 100 may not be lowered any longer.

In this case, most regions, other than the upper portion, of the display panel 100 may be placed at the lower wall 15 of the case 10.

According to an aspect of the present disclosure, the display panel 100 may be disposed in parallel with the lower wall 15 of the case 10. Depending on the case, the display panel 100 may protrude in the upward direction of the cover 20 covering the case 10.

Therefore, even when the case 10 is disposed at a plane of a desk or the like, the case 10 may not largely protrude from the plane of the desk. Also, even when the case 10 is disposed at a lower end of a desk or the like, the case 10 may not largely protrude in a direction toward the lower end of the desk. For example, a height of the sliding display apparatus according to an aspect of the present disclosure may be formed to be flat, and thus, even when the sliding display apparatus according to an aspect of the present disclosure is used with being buried into a desk or the like, an external appearance of the desk may not largely be damaged.
